which kind of memory card does he have now? some olympus dcs use xD
cards, some use SM cards. xD cards are relatively more expensive. I
feel the price of these two are just so so. Dell sometimes have
better deals

he doesn't have anything now. so either type of memory card is fine.

olympus的储存卡和电池你都先看看吧，他们有的用的不是CF卡，电池也不是能充电的那种。

这标题让我想起了“开心辞典”，全家人的梦想。。。。

还是表买olympus的数码相机啦，他家不是ｘＤ就是ＳＭ卡，太贵了。。。。ｃａｎｏｎ和ｎｉｋｏｎ的都很好啊

那佳能的什么型号好呢？
